Health A to Z
A lung transplant is an operation to remove and replace a diseased lung with a healthy human lung from a donor.
A donor is usually a person who's died, but in rare cases a section of lung can be taken from a living donor.
Lung transplants aren't carried out frequently in the UK. This is mainly because of the lack of available donors. In England, during 2013-14, 198 lung transplants were carried out.
A lung transplant will often be recommended if:
Conditions that can be treated with a lung transplant include:
There are three main types of lung transplant:
The demand for lung transplants is far greater than the available supply of donated lungs. Therefore, a transplant will only be carried out if it's thought there's a relatively good chance of it being successful.
For example, a lung transplant wouldn't be recommended for someone with lung cancer because the cancer could reoccur in the donated lungs.
You also won't be considered for a lung transplant if you smoke.
It's possible for a person to receive a lung transplant from living donors (two living donors are usually required for one recipient). However, lung transplants from living donors are currently rare in the UK.
During this type of lung transplant, the lower lobe of the right lung is removed from one donor, and the lower lobe of the left lung is removed from the other donor. Both lungs are removed from the recipient and replaced with the lung implants from the donors in a single operation.
Most people who receive lung transplants from living donors have cystic fibrosis and are close relatives of the donors. The recipient and donors need to be compatible in size and have matching blood groups.
Before being placed on the transplant list you'll need to have some tests to make sure your other major organs, such as your heart, kidneys and liver, will function properly after the transplant.

A lung transplant usually takes between four and 12 hours to complete, depending on the complexity of the operation.
A cut is made in your chest and the damaged lungs removed. Depending on your individual circumstances, you may be connected to a heart and lung bypass machine to keep your blood circulating during the operation.
The donated lungs will then be connected to the relevant airways and blood vessels and the chest will be closed.

A lung transplant is a major operation that may take at least three months to recover from. It could be quite a while before you're able to return to work so you'll need to make necessary arrangements with your employer.

A lung transplant is a complex type of surgery that carries a high risk of complications.
A common complication is the immune system rejecting the donated lungs. As a result of this, a medication known as an immunosuppressive is given to dampen the effects of the immune system, reducing the risk of rejection. However, taking immunosuppressives carries its own risks as they increase the chances of infection.

The outlook for people who've had a lung transplant has improved in recent years and it's expected to continue improving.
The British Transplantation Society estimates that around nine out of 10 people survive a lung transplant, with most of these surviving for at least a year after having the operation.
About five out of 10 people will survive for at least five years after having a lung transplant, with many people living for at least 10 years. There have also been reports of some people living for 20 years or more after a lung transplant.
Although complications can occur at any time, a serious complication is most likely to occur in the first year after the transplant.
If a lung transplant is thought to be an option for you, you'll be referred for a transplant assessment.
There are a number of specialist centres that carry out lung transplants in England. They are:
A small number of children's lung transplants are carried out at Great Ormond Street Hospital and Freeman Hospital.
You'll need to stay in hospital for up to three days for a lung transplant assessment.
Tests will be carried out to make sure your other major organs, such as your heart, kidneys and liver, will function properly after the transplant. These may include blood tests and any of the following investigations:
During the assessment, you'll be able to meet members of the transplant team and ask questions. Your transplant team will include:
The transplant co-ordinator will be your main point of contact. They'll talk to you and your family about what happens during a lung transplant and the risks involved.
After the assessment is complete, a decision will be made as to whether a lung transplant is suitable for you and whether it's the best option.
It may be decided that:
The supply of donor lungs is limited, which means there are more people who would benefit from a lung transplant than there are donor lungs.
Therefore, people who are unlikely to have a successful transplant aren't usually considered suitable for transplant.
You may also be considered unsuitable if:
Age also plays a part, because of the effect it has on likely survival rates. There are no set rules and exceptions can always be made, but as a general rule:
Once you're on the active waiting list, the transplant centre may give you a pager so you can be contacted at short notice.
The length of time you'll have to wait will depend on your blood group, donor availability and how many other people are on the list (and how urgent their cases are).
While you wait, you'll be cared for by the doctor who referred you to the transplant centre. They'll keep the transplant team updated with changes to your condition. Another assessment is sometimes necessary to make sure you're still suitable for a transplant.
Your transplant team will often be given short notice of donor organs, so will have to move swiftly. When a suitable donor is found, you'll usually need to be in hospital ready for your transplant within six to eight hours. If you live a long way from a transplant centre, you'll be flown to the centre or taken by ambulance.
When a suitable donor lung is found, the transplant centre will contact you and ask you to go to the centre.
When you hear from the transplant centre:
At the transplant centre, you'll be quickly reassessed to make sure no new medical conditions have developed. At the same time, a second medical team will examine the donor lungs.
The lung transplant must be carried out as quickly as possible to ensure it has the best possible chance of being successful.
A lung transplant usually takes between four and 12 hours, depending on the complexity of the operation.
After you've had a general anaesthetic, a breathing tube will be placed down your throat so your lungs can be ventilated.
The surgeon will make an incision in your chest so that your chest can be opened and preparations made to remove the diseased lung or lungs.
If assistance with your circulation is needed, a cardiopulmonary bypass machine may be used to keep your blood circulating during the operation.
The old lung will be removed and the new lung sewn into place. When the transplant team is confident the new lung is working efficiently, your chest will be closed and you'll be taken off the bypass machine.
Tubes will be left in your chest for several days to drain any build-up of blood and fluid.
You'll be taken to the intensive care unit, where more tubes will be attached to supply your body with medication and fluids and to drain urine from your bladder.
There are two new surgical techniques that will hopefully increase the number of donor lungs available for donation. These are described below.
Most donations are from people who've died but whose heart is kept beating using life-support equipment. These are often people who've died following a long illness.
It's now also possible for lungs to be taken from a person who's died suddenly, and to keep their lungs "alive" for around an hour by passing oxygen into them. The oxygen keeps the biological processes of the lungs going, which preserves them.
Lungs can be damaged when the brain dies, before they're removed for donation. As a result of this, only one in five lungs are suitable for donation.
Ex vivo lung perfusion is a new technique designed to overcome this problem. It involves removing the lungs from the body and placing them in a special piece of equipment called a perfusion rig.
Blood, protein and nutrients are then pumped into the lungs, which repairs the damage.
The technique is still in its infancy, but hopefully it will eventually lead to an increase in the number of lungs available for donation.
A lung transplant is a complex operation and the risk of complications is high.
Some complications are related to the operation itself. Others are a result of the immunosuppressive medication which is needed to prevent your body rejecting the new lungs.
Some of the complications are discussed below.
Reimplantation response is a common complication affecting almost all people with a lung transplant. The effects of surgery and the interruption to the blood supply cause the lungs to fill with fluid.
The symptoms are usually at their worst five days after the transplant. These problems will gradually improve, and most people are free of symptoms by 10 days after their transplant.
Rejection is a normal reaction of the body. When a new organ is transplanted, your body's immune system treats it as a threat and produces antibodies against it, which can stop it working properly. Most people experience rejection, usually during the first three months after the transplant.
Shortness of breath, fatigue (extreme tiredness), and a dry cough are all symptoms of rejection, although mild cases may not always cause symptoms.
Acute rejection usually responds well to treatment with steroid medication.
Bronchiolitis obliterans syndrome (BOS) is another form of rejection that typically occurs in the first year after the transplant, but could occur up to a decade later.
In BOS, the immune system causes the airways inside the lungs to become inflamed, which blocks the flow of oxygen through the lungs.
BOS may be treated with additional immunosuppressant medications.
After having a lung transplant, your risk of developing a lymphoma (usually a non-Hodgkin lymphoma) is increased. This is known as post-transplantation lymphoproliferative disorder (PTLD).
PTLD occurs when a viral infection (usually the Epstein-Barr virus) develops as a result of the immunosuppressants that are used to stop your body rejecting the new organ.
PTLD affects around one in 20 people who have a lung transplant. Most cases occur within the first year of the transplant. It can usually be treated by reducing or withdrawing immunosuppressant therapy.
The Lymphoma Association has more information about lymphomas after organ transplantation (PDF, 232kb).
The risk of infection for people who've received a lung transplant is higher than average for a number of reasons, including:
Common infections after a transplant include:
Taking immunosuppressant medications is necessary following any type of transplant, although they do increase your risk of developing other health conditions.
These health conditions are described below.
Kidney disease is a common long-term complication. It's estimated that one in four people who receive a lung transplant will develop some degree of kidney disease a year after the transplant.
About 1 in 14 people will experience kidney failure within a year of their transplant, rising to 1 in 10 after five years.
Diabetes, specifically type 2 diabetes, develops in around one in four people a year after the transplant.
Diabetes is treated using a combination of:
High blood pressure develops in around half of all people a year after a lung transplant and in eight out of 10 people after five years.
High blood pressure can develop due to a side effect of immunosuppressants or as a complication of kidney disease.
Like diabetes, high blood pressure is treated using a combination of lifestyle changes and medication.
Osteoporosis (weakening of the bones) usually arises as a side-effect of immunosuppressant use.
Treatment options for osteoporosis include vitamin D supplements (which help strengthen bones) and a type of medication known as bisphosphonates, which help maintain bone density.
People who have received a lung transplant have an increased risk of developing cancer at a later date. This would usually be one of the following:
Because of this increased risk, regular check-ups for these sorts of cancers may be recommended.
After lung transplant surgery, you'll remain in the intensive care unit for around one to seven days.
You'll be carefully monitored so the transplant team can check your body is accepting the new organ. Monitoring will include having regular lung X-rays and lung biopsies (where tissue samples are taken for closer examination).
The transplant team will be able to see whether your body is rejecting the lung from the biopsy results. If it is, you'll be given additional treatment to reverse the process.
When your condition is stable, you'll be moved to a high-dependency ward, where you'll stay for one or two weeks.
You'll probably be discharged from hospital two to three weeks after surgery and asked to stay near the transplant centre for one month so that you can have regular check-ups.
For the second month, you'll need to visit weekly for four weeks. After that, for the rest of your life, you'll have a blood test every six weeks and will be seen at the transplant centre every three months.
It usually takes at least three to six months to fully recover from transplant surgery. For the first six weeks after surgery, avoid pushing, pulling or lifting anything heavy. You'll be encouraged to take part in a rehabilitation programme involving exercises to build up your strength.
You should be able to drive again four to six weeks after your transplant, once your chest wound has healed and you feel well enough.
Depending on the type of job you do, you'll be able to return to work around three months after surgery.
You'll need to take immunosuppressant medications, which weaken your immune system so your body doesn't try to reject the new organ.
There are usually two stages in immunosuppressant therapy:
You'll need to have maintenance therapy for the rest of your life.
Most transplant centres use the following combination of immunosuppressants:
The downside of taking immunosuppressants is that they can cause a wide range of side effects, including:
Your doctor will try to find an immunosuppressant dose that's high enough to "dampen" the immune system, but low enough that you experience few side effects. This may take several months to achieve.
Even if your side effects become troublesome, you should never suddenly stop taking your medication because your lungs could be rejected.
Long-term use of immunosuppressants also increases your risk of developing other health conditions such as kidney disease (read more about the risks associated with long-term immunosuppressants use).
Having a weakened immune system is known as being immunocompromised. If you're immunocompromised, you'll need to take extra precautions against infection. You should:
You should also look out for any initial signs that may indicate you have an infection. A minor infection could quickly turn into a major one.
Tell your GP or transplant centre immediately if you have symptoms of an infection, such as:
Born with cystic fibrosis, Sammi Sparke is now embarking on a new life thanks to an organ donor who gave her a new set of lungs, and her father's donation of a kidney.
Before her lung transplant, Sammi, from St Neots, Cambridgeshire, was desperately ill and housebound, barely able to walk.
"I wasn't particularly conscious of my cystic fibrosis for most of my life, but in the three years before my lung transplant, I was very ill. I'd always had occasional intravenous antibiotics and spent time in hospital, but I never considered it as anything other than an obstacle to overcome," says Sammi.
In 1998, Sammi developed pneumonia after an operation on her lungs, and doctors told her she needed a lung transplant.
"I was shocked to learn from my consultant that I wasn't going to get any better, as I'd always bounced back in the past. They said I should consider transplantation, and having to accept I was really ill made me depressed. I felt my life was over.
"I had some unusual medical problems, and for a time there was a question mark over whether they would attempt the transplant. I was so relieved when they said I could be registered for it. I'd seen friends have transplants and do very well, and I'd seen other people with cystic fibrosis die because a donor wasn't found in time. It was a very scary time."
Sammi had to give up her media studies degree in her second year because the disease left her housebound and almost helpless.
"I'd pass the time watching television and was inspired by travel programmes. I began to plan trips abroad for when I was well enough and started an Open University degree. Some days were better than others. I felt that all I had to cling to was the belief that one day I was going to receive the new lungs that would save me – that someone out there would be kind enough to donate them to me."
A donor was eventually found to match Sammi's needs, and she had a double lung transplant at Papworth Hospital, Cambridgeshire, in August 2002.
"The difference after the operation was instantaneous. As soon as I woke up, I didn't want to cough anymore. It was incredible. I could take a deep breath for the first time in years. I was still very weak after months being housebound as my muscles had wasted away, but otherwise I felt very well and recovered from the operation quickly."
Sammi enjoyed a new lease of life for two years following the transplant, but she had a setback when her kidneys failed due to the anti-rejection medication she was taking. Sammi's father stepped in to offer her one of his kidneys.
After the kidney transplant operation, she undertook a nine-month world trip, fulfilling the plans she'd made when waiting for her lung transplant.
